Abstract

The invention belongs to the technical field of electric power broadband carrier HPLC (High Performance Liquid Chromatography), and particularly relates to a high-speed and reliable Internet of Things electric power broadband carrier HPLC, which comprises a shed body, a shed roof, a combustion furnace, a water tank and a controller, comprising a mounting box, a circuit board, a sending unit, a triggering unit, an input unit, an interconnection unit, a storage database and a noise reduction unit, the mounting box comprises a rubber box and a metal ring; the vertical section of the metal ring is designed to be in a rectangular frame shape. The two rubber boxes are fixedly connected to the two sides of the metal ring respectively, and the rubber boxes are symmetrical about the metal ring. The inner wall of the metal ring is fixedly connected with rubber rods which are uniformly arranged; the rubber rod is made of a hard rubber material, the end part of the rubber rod is in contact with and extrudes the surface of the circuit board through a soft rubber block, and the circuit board is positioned in the mounting box; the signal transmission quality is high, the time of a high-noise section is short, the bandwidth loss in the signal transmission process is effectively reduced, meanwhile, the service life is long, and the application range is wide.

Description

technical field [0001] The invention belongs to the technical field of power broadband carrier HPLC, in particular to high-speed and reliable Internet of Things power broadband carrier HPLC. Background technique [0002] HPLC is a high-speed power line carrier, also known as broadband power line carrier, which is a broadband power line carrier technology for data transmission on low-voltage power lines. The broadband power line carrier communication network is a communication network that uses power lines as the communication medium to realize the aggregation, transmission and interaction of low-voltage power users' electricity consumption information. Broadband power line carrier mainly adopts Orthogonal Frequency Division Multiplexing (OFDM) technology, and the frequency band uses 2MHz-12MHz. Compared with the traditional low-speed narrowband power line carrier technology, HPLC technology has large bandwidth and high transmission rate, which can meet the higher requiremen...
